Online Practice Quizzes

The practice quizzes below include around 10 questions. They might last
a little longer as the questions sometimes change based on the answers
given to previous questions.

Some of the practice questions include hints and explanations. These are
only shown when previous answers in the quiz suggest they might be
required. The first set of quizzes are on addition and cover the often
tricky "bridging over" 10 and multiples of 10. The hints show how 10 and
multiples of 10 can be used as a "stepping stone" to get to the answer.
